Metatron (MNRJ) is a “Pure Play” App Company-one of the few now public.

“Pure play” companies are those whose main focus is building mobile apps, primarily iPhone/iPad, and most are private. Between 2008 and 2009, there were 11 investment rounds over 10 companies, with almost US$38 million raised.   Although Metatron has other divisions, I-mobilize is its main focus and revenue driver.

This year, over the same time period, there were 17 investment rounds distributed over 16 companies for a total investment of $120.6 million. The average deal was $7.5 million, up from an average of $3.4 million in the previous year.

The $102.49 million overall figure may be conservative since it leaves out a developers who create apps across smartphone platforms, like Metatron and I-mobilize.

According to Citibank, the App Store will continue to be a major money maker for Apple, and they’re estimating it will see $2 billion in sales in 2011. According to estimates by Gartner, the global app market brought in $4 billion last year, and will skyrocket to $27 billion in 2013 — that’s not chump change, which explains the investor interest in app companies.
